PURPOSE: A radiating structure of a PCB(Printed Circuit Board) for a washing machine is provided to maximize a radiating effect by mounting radiating fins having a good heat transfer rate. CONSTITUTION: Various electronic elements are mounted to a PCB. A heat sink is mounted with contacting to the PCB to radiate a heat from the PCB. A PCB case(50) covers the PCB and the heat sink. A plurality of radiating fins(53) are mounted erectly to an outer surface of the PCB case(50) to increase contact areas between the PCB case(50) and the surrounding air. The radiating fin(53) is formed by a thin plate having a good heat transfer rate. The fins(53) may be formed by a die casting work. Also, the PCB case may be formed with a plurality of crease-shaped prominences at its outer surface. The crease-shaped prominences may be formed by a press work.
